Abstract
殺蟎劑對二點葉蟎(Tetranychus urticae (Koch))，加州捕植蟎(Amblyseius californicus (McGregor))的毒陸依藥劑種類不同而有差異。合成除蟲菊類(synthetic pyrethroids)，有機磷劑(organophosphates)及氨基甲酸監類(carbamates)藥劑對這二種蝸類有較高的選擇性比值(selective ratio)。其餘類型殺蟎劑對捕植蟎、葉蟎毒性接近。Bromopropylate, binapacryl, dinobuton, propargite, oxythioquinox, smite及azocyclotin七種藥劑對葉蟎、捕植蟎之LC50。選擇比更小於1，是綜合防治時可考慮使用的殺蟎劑。The responses of two-spotted spider mite, Tetranychus urticae (Koch) and their predator, Amblyseius californicus (McGregor) to acaricides tested were different. The selective ratio between the spider mite and predatory mite was depended on the chemical structure of acaricides. Generally, synthetic pyrethroids, organophosphates and carbamates are more toxic to the predatory mite than to two-spotted spider mite, and resulted high selective ratios. Other groups of acaricides stated safer to the predatory mite, usually, the LC5, selective ratios were less than 4.
